Frequently asked questions

How many flashcards should I make from one PDF chapter?

Aim for one card per distinct fact, date or cause, so a dense chapter may need several dozen cards and a short handout may need only a few. Split any card that tests two ideas at once.

How should I study World War II events with flashcards?

Put the cause and outcome on the back, not just the event name, so you remember why it mattered. Keep daily sessions short and review the cards you miss most often.

Can I export my flashcards to PDF?

Yes, PDF export is included with the Plus plan at $99.90 per year or $9.99 per month. The Free plan lets you study in the browser without exports.

Do I need a credit card to try it?

No, you can start on the Free plan with 3 generations per month and no credit card. Students with a school email get 40% off Plus.
